摘要： A multilayered molding is disclosed, which has a base molding outer layer mainly composed of a partial crosslinking type substance A obtained from polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or a mixture B of polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or both. The outermost layer is in direct contact with and forms a lamination with an inner intermediate layer or a base molding composed of a polyethylene resin, for instance, and is firmly bonded to the outermost layer. A method of manufacturing such multilayered molding is also disclosed, in which a composite sheet of the thermoplastic elastomer with or without the intermediate layer is preliminarily heated, followed by being suction held in close contact with a mold cavity inner surface, thus forming a surface layer. The mold is then clamped, and fluidized and plasticized polyolein resin is injected to produce the molding. The polyolefin resin may also be injected prior to the clamping.

摘要翻译：公开了一种多层成型体，其具有主要由聚烯烃树脂和乙烯-α-烯烃共聚物橡胶得到的部分交联型物质A或聚烯烃树脂和乙烯-α-烯烃共聚物橡胶的混合物B的基础成型外层，或都。最外层例如与内部中间层或由聚乙烯树脂构成的基底模塑件直接接触并形成层压，并且牢固地结合到最外层。还公开了制造这种多层成型体的方法，其中预先加热具有或不具有中间层的热塑性弹性体的复合片材，然后与模具腔内表面紧密接触地吸附，从而形成表面层。然后将模具夹紧，并注入流化和增塑的聚烯烃树脂以制备模制品。聚烯烃树脂也可以在夹紧之前被注入。
